His upcoming new show Body Hack, the subject of today's cover story, features Sampson ditching his beloved t-shirts for a series of intense physical and mental challenges.

He's particularly nervous about the episode where he has a go at being a stuntman in a Bollywood movie.

"When that comes out I'm going into hiding because it's so embarrassing,” he laughs. "I do this love scene with this Indian actress and I think my wife will be more upset with that than anything else in the show.”
